TERRA-NG v1.0: Extreme-Scale, GPU-accelerated Mantle Convection
Fabian Böhm, Nils Kohl, Ponsuganth Ilangovan +7
We present TERRA-NG, a portable, GPU-accelerated, matrix-free mantle-convection code. A single Kokkos C++ implementation runs at scale on NVIDIA, AMD, and Intel GPU supercomputers.…
Code Generation and Performance Engineering for Matrix-Free Finite Element Methods on Hybrid Tetrahedral Grids
Fabian Böhm, Daniel Bauer, Nils Kohl +5
This paper introduces a code generator designed for node-level optimized, extreme-scalable, matrix-free finite element operators on hybrid tetrahedral grids. It optimizes the local…
Fundamental Data Structures for Matrix-Free Finite Elements on Hybrid Tetrahedral Grids
Nils Kohl, Daniel Bauer, Fabian Böhm +1
This paper presents efficient data structures for the implementation of matrix-free finite element methods on block-structured, hybrid tetrahedral grids. It provides a complete cat…
